FRAMEWORK FOR VACUUM-CLEANER CARPET-SWEEPERS.

Specification of Letters Patent.

Patented Mar. 15, 1921.

Application filed April 26, 1920. Serial No. 376,676.

To all whom it may concern:

Be it known that I, IRA J. OWEN, a citizen of the United States,residing at Grand Rapids, Kent county, Michigan, have invented certainnew and useful Im rovements in Framework for VacuumleanerCarpet-Sweepers, of which the followlng 1s a specification.

This invention relates toimprovements in general features of theframework of vacuum cleaner carpet sweepers.

The object of the invention is to provide a convenient and effectivemeans and construction lending itself to ready standardization andassembly of the parts.

Objects which relate to details Wlll definitely appear from the detaileddescriptlon to follow.

I accomplish the objects of my invention by the devices and meansdescribed 1n the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is fullyillustrated in the accompanying drawing, forming a part of thisspecification, in which:

Figure I is a side elevation View of a combination vacuum cleaner andcarpet sweeper embodying the features of my invention, with the partscompletely assembled.

Fig. II is a detail side elevation view with the interior sweeper andbellows supportlng frame dropped out of the case and left injuxtaposition thereto to show the method of assembling, portions of theouter case belng broken away to show details.

Fig. III is a detailtransverse sectional view taken on line 33 of Fig.I, looking in the direction of the little arrows at the ends of thesection line.

In the drawings similar numerals of reference refer to similar partsthroughout the several views.

Considering the numbered parts of the drawing, 1 is the outer shell orcasing whlch is here made in the form of an open bottom box of suitableform, notched at the front to accommodate the nozzle block 3. 2 is theinner casing or box which carries the carpet sweeper 4 below andcontains the vacuum chamber 5 within which is disposed the dust bag 5above the carpet sweeper, andon 1ts upper wall 6 carries the bellows 6,so that within this casing, in a suitable unitary and the tops of thewheels extend above the bottom at each side. The bellows 6' areconnected by suitable detachable pitmen 6 to the crankshaft 10 at therear. The propelling wheels 8 for the vacuum cleaner carry this crankshaft. These are made conveniently detachable by hanger blocks 9 whichare supported in place on the outer case by screws 11 (Fig. I), makingthe assembling of arts a very simple operation.

y providing the outer case with the vacuum cleaner floor wheels thusdisposed 1n the rear thereof and providing the carpet sweeper andbellows structure in a unitary structure on an internal box which can bereadily removed bodily from the machine, assembling and repair aregreatly facilitated. The entire operating parts of the bellows andcarpet sweeper can be made up in plain lumber, yet the outer case can begiven a handsome finish to drop over the same, and by locating thevacuum cleaner driving means in the space at the rear of the machine andproviding these driving means wlth hangers that are readily detachable,it will be seen that a standardization of structure is possible in allparticulars, so that to produce the different grades of vacuum cleanersand sweepers it is only necessary to select and assemble the differentand appropriate parts.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. In a vacuum cleaner and carpet sweeper, the combination of an outercasing open at the bottom, with driving floor wheels and crank shaftdisposed in the rear for driving the vacuum cleaner, an internal,unitary, removable, box-like structure at the front thereof, the upperwall of which constitutes a bellows board, a vacuum chamber beneath thesaid board, a carpet sweeper beneath the vacuum chamber supportedbetween the side walls of said box, and a suitable nozzle block at thefront of said vacuum chamber conformed and fitted to the outer casing,all coacting substantially as described for the purpose specified.

2. In a vacuum. cleaner and carpet sweeper, the combination of an outercasing open at the bottom, with driving floor Wheels suitably securedthereto, a removable, uintary box-like structure at the front thereofcomprising a bellows and vacuum chamber and carpet sweeper structure,and a suitable nozzle box at the front of said unitary structure andconformed and fitted to the outer casing, as specified.

In witness whereof, I have hereunto set 15 my hand and seal in thepresence of two witnesses.
